A kind of preparation method of nbr/pvc/mxdp high wear-resistant rubber material

Abstract

A preparation method of NBR / PVC / MXDP high wear-resistant rubber material, relates to a preparation method of rubber material, the proportion is by weight, and its components include 100 parts of NBR / PVC alloy, 1-14 parts of wear-resistant agent, 50-60 parts of carbon black, 6-8 parts of vulcanization activator, 1-3 parts of anti-aging agent, 4-6 parts of softener, 2-3 parts of crosslinking agent, 0.5-1 part of auxiliary crosslinking agent, 1 part of plasticizer ‑20 servings. Add the NBR / PVC alloy to the torque rheometer, and then add the ternary nylon; pass the mixture of the NBR / PVC alloy and the ternary nylon after the torque on the open mill for 4 times, and then add zinc oxide, hard Fatty acid, softener, anti-aging agent, protective wax, after mixing evenly, add carbon black and plasticizer in turn, further mixing and finally add DCP, TAIC; after that, rubber mixing and vulcanization. The invention improves the tensile strength and wear resistance of the vulcanized rubber through the use of ternary nylon and the use of NBR / PVC alloy as rubber.

Description

technical field [0001] The invention relates to a preparation method of a rubber material, in particular to a preparation method of an NBR / PVC / MXDP high wear-resistant rubber material. Background technique [0002] The rubber liner has the advantages of light weight, low power consumption, convenient maintenance, low product cost, good economic benefits, low noise, etc. It has been widely used in mine screening, but now the rubber liner has poor wear resistance and short service life. Therefore, it is imperative to develop a rubber lining with good wear resistance and long service life. NBR / PVC alloy has good oil resistance, heat resistance, wear resistance, air tightness and chemical corrosion resistance; ternary nylon has excellent creep resistance and fatigue resistance, good wear resistance and small friction coefficient , the amount of wear is small, it is suitable for some parts that need long-term wear, and because it has internal lubrication, it does not need lubric...

[0002] The rubber liner has the advantages of light weight, low power consumption, convenient maintenance, low product cost, good economic benefits, low noise, etc. It has been widely used in mine screening, but now the rubber liner has poor wear resistance and short service life. Therefore, it is imperative to develop rubber liners with good wear resistance and long service life

NBR / PVC alloy has good oil resistance, heat resistance, wear resistance, air tightness and chemical corrosion resistance; ternary nylon has excellent creep resistance and fatigue resistance, good wear resistance and small friction coefficient , the amount of wear is small, it is suitable for some parts that need long-term wear, and because it has internal lubrication, it does not need lubrication during use, and it can overcome or reduce the heat generation phenomenon when used under dynamic conditions, and maintain the stability of the material. Stability; therefore, adding ternary nylon to nitrile rubber will greatly improve the physical and mechanical properties of vulcanized rubber. In addition, NBR / PVC alloy is used to produce rubber liners, and ternary nylon, NAPM and liquid are added to it. Nitrile has not been reported
